Title
- In the context of the renovation of old buildings in Europe, our SIP roof panels offer an ideal solution for replacing outdated structures with modern, energy-efficient systems. Panels can be mounted without rafters, which then use the entire attic space.
- A roof made of SIP panels allows you to make the building more energy efficient, much faster than installing rafters and insulation separately, and also significantly minimizes the number of “cold spots”, because all elements have an ideal geometry and are tightly fitted together.
- Another great advantage is the ability to mount solar stations on the roof, because the SIP panel roof has a strong structure and allows you to easily install solar panels without additional equipment for reinforcement and fasteners. Use photovoltaic tiles and get a ready-made rooftop solar station in one installation.
Benefits for builders
Load capacity of roofs made of Ecopan panels
The value of the roof load
Designed for use class 2 according to EN 1995-1-1. The maximum span between supports is 1250 mm. The calculation model is valid in the case of undivided cladding on both sides of the Ecopan panels. The mechanical properties of the insulating filler used in the calculation model are given in the table below. In the calculation model, slotted joints and Ecopan ridge beams are used. Ecopan slotted joints and ridge beams give the same mechanical resistance results
Load value
The load values are calculated values according to EN 1995-1-1 and relevant EN standards. The actual load of the panel is included in the calculation. Characteristics of OSB/3 according to EN 12369-1. The strength class of wooden elements is C24 according to EN 338.
Considering the modification, the deformation and partial coefficients (kmod, kdef, γm) should be used according to EN 1995-1-1, taking into account the duration of the load and the corresponding class of operation.
Title
Ecopan can produce panels in different thicknesses allowing us to achieve very low heat transfer coefficient values, our u values can range from 0.29 W/m².K to 0.15 W/m².K, a detailed table of heat transfer coefficients for different characteristics can be found in the Technology section
Sections show an example of SIP roof construction to achieve thermal performance.
